APPARATUS AND A METHOD FOR COMPENSATING PHASE ERROR IN A WIRELESS COMMUNICATION SYSTEM, PARTICULARLY FOR REDUCING THE PERFORMANCE DEGRADATION DUE TO THE CHANNEL ESTIMATION

摘要

PURPOSE: An apparatus and a method for compensating phase error in a wireless communication system are provided to estimate the interference channel between the self interference channel or antenna interference channel.;CONSTITUTION: A first channel estimator(403) presumes the channel about each burst using the signal received from the transmit modem and the signal received from the CPE compensator. A phase compensator(405) compares phase toward the channel of each burst received from the first channel estimator. The phase compensator compensates the phase difference of bursts. A second channel estimator(407) presumes the interference channel in consideration of the channel of two or more bursts in which the phase difference is compensated.;COPYRIGHT KIPO 2011
